8.7 Alarms

 Sounding the ship’s alarms/whistle serves to inform the vessel’s crew that a piracy attack has commenced and, importantly, demonstrates to any potential attacker that the ship is aware of the attack and is reacting to it. If approached continuous sounding of the vessels foghorn/whistle distracts the pirates and as above lets them know that they have been seen. It is important to ensure that:

  • The piracy alarm is distinctive to avoid confusion with other alarms, potentially leading to the crew mustering at the wrong location outside the accommodation.
  • Crew members are familiar with each alarm, including the signal warning of an attack and an all clear, and the appropriate response to it.
  • Exercises are carried out prior to entering the High Risk Area.
